When type B agglutinogen is not present on the surface of RBC of a person, his plasma would contain ____ agglutinins.

1. Anti-a                          2. Anti-b

3. Both anti-a and anti-b   4. None

A person with AB blood group:

1. Has A and B antigens in his plasma

2. Lacks any antibodies on RBC surface

3. Can receive blood transfusion from a person of his own group.

4. Can donate blood to all other group recipients

Person with blood group AB is considered as universal recipient because he has

1. Both A and B antigens on RBC but no antibodies in the plasma

2. Both A and B antibodies in the plasma

3. No antigen on RBC and antibody in the plasma

4. Both A and B antigens in the plasma but no antibodies.

A person with unknown blood group under ABO system, has suffered much blood loss in an accident and needs immediate blood transfusion. His one friend who has a valid cetificate of his own blood type, offers for blood donation without delay. What would have been the type of blood group of the donor friend?

(1) Type AB

(2) Type O

(3) Type A

(4) Type B

The universal donor and acceptor will be–

(1) O^– and AB^–

(2) O^– and AB⁺

(3) O⁺ and AB^–

(4) O⁺ and AB⁺

ABO blood grouping is based on

(1) presence of two soluble antibodies

(2) absence of two surface antigens

(3) presence of two surface antigens

(4) both (2) and (3)

If a person is AB ^– , who cannot donate blood to this person?

(1) any person with Rh antigen

(2) any person with O⁺ only

(3) any person with AB^–

(4) all people except A⁺

A person with blood group O^– can take blood from

(1) O⁺ person

(2) O^– person

(3) A⁺ person

(4) both (1) and (2)

When the plasma of a person has both anti A and anti B antibodies the blood group of this person would be:

1.  A

2.  B

3.  AB

4.  O

The most popularly known blood grouping is the ABO grouping. It is named ABO and not ABC, because 'O' in it refers to having:
